first day of my college

eh, I am tired but it was interesting. i got the chance to go around my campus and get to know some people there. i was so excited that i didn't fall asleep that night. I have had the desire to want to know something for days, so i used two days to get a better impression of this new city, this new school. i like all my classmate now. they are nice and kind. they help with the things i don't know. they are my life saver at some level.

Very good. Those are the only little pieced I would change to make it sound more natural.

Good job, but carefully with your spelling. 

Carefully with tenses, you can't mix them. 

If you need any help more, feel free to ask me.
